41、DSCC FORM 2234 APR 97 Notes: 1. At full page mode, burst is end at the end of burst. So auto precharge is possible. 2. Data-in at the cycle of interrupted by precharge can not be written into the corresponding memory cell. It is defined by AC parameter of tRDL. DQM at write interrupted by precharge
42、command is needed to prevent invalid write. DQM should mask invalid input data on precharge command cycle when asserting precharge before end of burst. Input data after Row precharge cycle will be masked internally. 3. Burst stop is valid at every burst length. FIGURE 5. Timing waveforms Continued.

BRSW modes is enabled by setting A9 “Hi
44、gh” at MRS(Mode Register Set). At the BRSW Mode the burst length at write is fixed to “1” regardless of programmed burst length. 2. When BRSW write command with auto precharge is executed, keep in mind that tRASshould not be violated. Auto precharge is executed at the burst-end cycle, so in the case of BRSW write command, the next cycle starts the precharge. FIGURE 5. Timing waveforms Continued.
